Mixer making sounds and Audio Dropout


hmm… grounding problem? if yes, it can be solved by opening the screws of it to reconnect the contacts or so…

so far…


Hmm… if that’s the culprit, it’s a bit of a weird design quirk considering there should be many screws to do that job with some redundancy. If it is persistent and you suspect that is indeed the cause, you might want to try removing some of those screws, bathing them in some 3-in-1 oil from WD 40, and then (with just small amounts of the the oil left on them after they’ve soaked overnight) screwing them back in. 3-in-1, in my experience, can do wonders with getting rid of corrosion, improving conductive contacts, and even cleaning and lubing faders (faders in alcohol bath first is even better). You obviously don’t want the screws dripping with it, though, when you put them back in, as that can make a mess.


Unless this “advice” is listed, word for word, in the official manual, I wouldn’t suggest anyone take even one step toward their x1800 screws. Instead, print out the above post, cross it out with a thick highlighter, scrunch it up and practice your over-your-shoulder-across-the-room-eyes-closed, slam dunk basketball skills into the bin :basketball:


Seems like an unqualified response. Being that I own the X1800 and I’ve repaired DJ mixers before, including the DJM800 and InMusic’s first 24bit digital DJ mixer, the PPD01, if the newest InMusic design, the X1800, can’t handle the externally-accessible chassis screws being removed, cleaned, slightly lubed, and re-inserted, then it has much bigger problems than grounding issues. That being said, at this point there’s no way to be certain what’s causing this problem.


Any word from Denon how to solve this problem? Because this problem comes and goes with my X1800…


Like I had mentioned above, I seem to have solved my issue since the original post by just re flashing the firmware.

That being said I just acquired a backup mixer and will try to send my x1800 in this week. I will certainly post if anything new develops. I love my prime setup and will definitely continue to contribute to forum to help others!


Other than my last post, about getting a replacement under warranty, nothing new has come of this. Never got a response. SC5000M looks cool!


Hi guys, I just got the X1800 last friday and used it this weekend and I get the audio drop-out too. The X1800 soundcard is connected to my PC via USB. When I make a Windows test sound from the audio device menu, the sound is muddy, choppy and eventually cuts off and the test doesn’t complete or sometimes doesn’t play at all. When I do a similar test on the soundcard of my Mackie ProFX Mixer, I don’t have this problem and the test sound is crisp and clear. I have the latest firmware 1.1.1 and I have tried several settings in the utility section, other USB plug and different wires and still having the problem. I wouldn’t want this to happen to me in a live gig. Is it the same hardware issue or something else? I don’t hear humming in the back but the sound becomes distorted before I loose the sound completely. Help


Have you installed the Denon ASIO driver and adjusted usb buffer & latency according to your computers CPU power? Doesn’t seem like it. Anyway…your problem doesn’t seem to be anything similar to the OP.
